    When a typical 220KV substation of 5 breaker ring bus arrangement occupies an overall area of 100m*40m, the GIS for the same arrangement will require only 24m*9m area. Due to large density of SF 6 the thermal conductivity is also high, the ratio for the same SF6/air is 2.5:1. Hence the dissipation of the generated heat by the ohmic

  • SF6 Circuit Breakers - Construction, Types and Working

    In an SF6 Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium.. The sulphur hexafluoride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (SF6) gas and an arc is struck between them.
